Dear U-booters,
I'm in the process of writing my bachelor thesis about porting Linux to custom board made by a company here in Denmark. As a part of this process, I am also trying to port U-boot to the board with limited success so far, unfortunately.
As I've mentioned in the topic, it has a PXA270, with 16 megs of Intel Strata P30 flash and 16MB of some Mobile SDRAM MT48H8M16LF. As far as I'm aware, this should be a relatively common configuration...
I started off by basing my port on the balloon3, as it seemed to be very clean and similar in specs. I've set up the clocks, memory registers and gpios, but i seem to be hitting some weird issues.
First, here is my boot log:
U-Boot 2010.12-rc1-00026-g0c0892b-dirty (Nov 18 2010 - 15:51:10)

resetting ...
As far as I can tell, the bootloader successfully relocates itself into RAM but fails to allocate 72bytes for the environment.
Before someone mentions, yes, I have added some extra lines to try to trace back what could be going wrong..
I have attached a diff of my changes, hope you guys can help me.
Cheers,
